PLC Parameters
IOCANSPE (P88)
When using CAN connection, the transmission speed depends on the length of the cable or total
CAN connection distance.
Fagor modules that do not have a baudrate selector can only work at 500 Kbit/s.
IOCAGEN (P89)
Not used.
IOCANID1 (P90) IOCANID2 (P91) IOCANID3 (P92)
IOCANID4 (P93)
They are used to set the remote modules.
They indicate which remote module each PLC parameter group (ICAN*, OCAN*, NUICAN*,
NUOCAN*) refers to.
Assign the CAN bus address that occupies the node (the one indicated by the address selector
switch).
ICAN1 (P94) OCAN1 (P95) ICAN2 (P96) OCAN2 (P97)
ICAN3 (P98) OCAN3 (P99) ICAN4 (P100) OCAN4 (P101)
They are used to set the remote modules.
They indicate the configuration of each remote module, number of inputs (ICAN*) and outputs
(OCAN*).
Example for a remote module located in node 1, with 48 inputs and 32 outputs:
IOCANID1=1 CAN1=48 OCAN1=32
NUICAN1 (P102) NUOCAN1 (P103) NUICAN2 (P104)
NUOCAN2 (P105) NUICAN3 (P106) NUOCAN3 (P107)
NUICAN4 (P108) NUOCAN4 (P109)
They are used to set the remote modules.
Parameter NUICAN* indicates the number of the first digital input and NUOCAN* the number of the
first digital output for the group.
The first I/O module is always the CPU (8055i CNC without expansion board) or an axes board or
an I/O board (modular 8055 CNC).
In either case, the first input number is always I1 and the first output number O1 and they cannot
be set by parameters.
On remote module the inputs and outputs of the different elements are numbered sequentially. The
inputs and outputs are defined in groups of 8 and the possible values of NUICAN* and NUOCAN*
must be multiple of 8 plus 1 (8n +1).
If NUICAN=0 or NUOCAN=0, the group following the one assigned to the previous node is assigned
to the corresponding node.
Value Meaning
0 1 Mbit/s. Up to 20 meters.
1 800 kbit/s. From 20 to 40 meters.
2 500 kbit/s. From 40 to 100 meters.
3 250 kbit/s. From 100 to 500 meters.
4 125 kbit/s. From 500 to 1000 meters.
Default value: 2 (500 kbit/s)
If incoherent parameter settings are detected on power-up, an error message will be issued indicating
it.
